Toad whom it may 00.10am:

Be it known that I, GEORGE H. CHAPEL, a citizen of the United States ofAmerica, re-

ston. and State of Michigan, have invented certain new and usefulImprovements in E e 'lasses. of which the folloWm 1s a snecraccompanying drawings.

This invention relates to improvements in eye-glass mountings and moreparticularly to the construction and arrangement of fin pieces ofmountings and springs actuating the same.

The object of the invention is to provide a simple and cheapconstruction which is such as to greatly facilitate the assembling ofparts and to give a strong and rigid bearing for thefinger-piece, theconstruction also being such as to provide a ready attachment for thespning and give a very neat To these ends the invention consists in thematters hereinafter set forth and more particularly pointed out in theappended claims reference being had to the accompanyi 1g drawing inWl1lCl1- Figure 1 is an elevation of eyeglasses embodying the invention;Fig. 2 is an edge VlQW of the same; F 3 is an enlarged perspective viewof aportion of the mounting; Fig. i is an enlarged sectional detailthrough a portion of the mounting and finger piece and through thespring for actuating the ringer piece; Fig. 5 is an enlarged perspective view of a screw post; Fig. 6 is an enlarged detail of a portion ofa mounting show ng a plan View of Fig. 7 and illustrata modifiedconstruction and Fig. 7 is a sectional view of the detail shown in Fig.6 and showing parts in elevation.

As ill'ust'ated in the drawings .1, 1. represent-lenses which are heldin the usual man nor by means of clips 2 formed integral 'ith the endsof the bridge 3 in the usual manner. Between the ends oi the bowedportion broadened and somewhat thickened to form bearing portions a eachhaving an openin therein through which a post 5 extends and in whichsaid post is adapted to turn freely. The post has a reduced lower endportion 6 which forms a shoulder 7 intermediate the ends of the post andthe portion 6 is adapted to engage the opening in the bridge with itsshoulder resting upon the upper surface or the supporting p'ortiona ofthe bridge, The

upper end portion 8 of the post which is of grezter diameter than thelower portion 6 is pro oed with a siightly tapered laterally pro agdrugs at its upper end forming a slight head i) on the post- 'uhich isrounded to provide a smooth upper surface and give a neat appearance.This head is also formed with the usual transverse slot 10 for theengagement of a screw driver and. the body Sis formed with alongitudinal groove 11' in one side extending from. one end of the slot10.

A guard lever or". any suitable form and construction is attached to thelower projecting end of the post by screw-threading said end andscrewing it into a scrcwthread ed opening in the lever which is thusheld in engagement with the lat lower surface of the bearing portion a*uosite that surface which is eng ged hy the; shoulder 7 of'the post.The guard lever is constructed in the usual manner with a foz -u'ardlyprojecting A flat volute spring 1% is coiled about the' body 8 of thepost with one edge resting on the upper surface of the bearing portion 4of the bridge The inner end of the spring is inturned and engaged withthe slot 11 in the post and the outer end of the spring is turnedoutwardly to engage a lug 15 formed or secured to the bridge or adjacentclip member of the mounting. This lug has a lateraliy extending lip 16at its end to engage over the end oi the spring and hold the signing rai'nst its seat upon the bearing portion 4- r the bridgl-z. The flangedupper end or head 9 on the post also assists in holding the spring 1place upon its seat,

The spring so coiled about the post that it tends to turn the post insuch Zl;Cli1'6CtiOI1 that its screWthrad-ed lower end will be screwedinto the finger piece and thus preyent the accidental diseng fj'einentof the finger piece from the post The finger piece may he quit ly andca; detached for the purpose of replacement or repair by disengaging theend of the spring from the lug 15, removing the spring, and then turningthe post to disengage its screwthreaded end from the finger piece Whenthe parts are in place, the finger piece has firm rigid bearing by itsengagement with the under side of the bear'ng or support 4- of thebridge and the is attached in such a manner asto constantly i hold thescrew post against unscrewing, it

is unnecessary to rivet or otherwise permanently Secure the post to theguard lever. While the guard lever is firmly held against wabbling bythe post and the'broad bearing which it has against the bridge, the postturns freely in its bearing without binding sot-hat the spring will actupon the lever 4 through the medium of the post to turn the same andhold the guard in gripping position..': I In Figs. 6 and 7 a wire spring17 is shown coiled about the post in place of the volute fiat spring14:, one end of the spring 17 being inserted in the slot 10 of the postand support and the opposite end of the spring engaged with a suitableprojection on the bridge or against the adjacent clip. It is obviousthat the Wire .coiled spring operates in the same .manner that the fiatspring acts and that either formof springv may be used as de sired. l

Obviously changes may be made in the constructionand arrangement ofparts without departing from the spirit of'my invention and I .do nottherefore limit myself to the particular form or construction shown.

Having thus fully described my invention what I claim i$:-'- j I 1. Inan eye glass mounting the combination of a support, a guard lever at oneside 'of the support,-'a member having a bearing on the support to turntherein and about which the guard lever is attached, and a springattached to said member at the opposite side of said support to turn themember and guard lever.

2. In an eyeglass mounting, the combination of a support having anopening, a rotatable member within said opening, a guard lever attachedto said member at one side of said support and a spring acting upon saidmember at t e opposite side of the-support.

3 3. In an eye glass mounting the combination of a support havinganopening therein, a member rotatable within said opening, a bearing uponone side of the support, a guard lever attached to the rotatable memberin contact wit-lithe opposite side of said a spring attached to andcoiled about the rotatable member at the side of the support oppositethat engaged by the to said support.

4. In an eye glass mounting, the combinat on of a support having anguard lever to position said lever relatively post rotatable within theopening and having a shoulder to engage one side of the support, a guardlcvernttached to the post in contact with the opposite side of thesupport, and a spring to turn the post.

5. In an eye glass mounting, the combination of a support having anopening, a post havinga reduced end portion to engage the openingandturn therein, and an end portion having a slot, a guard lever attachedto the reduced end of the post in contact with one side of thesupport,and a coiled spring surrounding the post at the opposite side of thesupport with one end engaging the slot in the post to turn the same andposition the guard lever relatively to the support.

6. In an eye glass mounting the combinapost to turn freely within theopening and raving a screwthreaded end, a guard lever having ascrewthreaded opening engaged by the screwthreaded end of the post, anda spring coiled about the post to turn the post and holdits-screwthreaded end engaged with the guard lever.

7. In an eye glass mounting. the combination of a support having anopening, a guard lever engaging one side of the sup-port and v providedwith a screwthreaded opening, a post having a reduced end to turn withinthe opening and formed with a shoulder to -engage the side of thesupport opposite that engaged by the guard lever, said post having ascrewt-hreaded end to engage the screwthreaded opening in the guardlever, and a spring coiledabout the post and attached thereto to turnthe same, said spring resting upon said support at the side thereofopposite that engaged by the guard lever.

' 8. In an eye glass mounting, the combination of abridge having aportion forming a support provided with an opening, a guard lever havinga screwthreaded opening, a post having a reduced end projecting throughthe opening in the support and engaging the screwthreaded opening in theguard lever, said post being formed with a shoulder to engage the sideof the sup-port opposite that which is engaged by formed with alongitudinal slot in one side, a flat convolute spring surrounding thepost with one end engaging the slot in the post, saidspring resting uponthe support around the post, and a lug on the support to engage theopposite end of the spring.

In testimony whereof I my signature in presence of two witnesses.
